EDI-OCT evaluation of choroidal thickness in retinitis pigmentosa

European Journal of Ophthalmology, 2018
Purpose: To evaluate choroidal thickness (CT) in retinitis pigmentosa (RP) using enhanced depth imaging (EDI) optical coherence tomography (OCT). Methods: A retrospective analysis of a group of patients with RP who underwent EDI-OCT was performed ...

Automatic measurements of choroidal thickness in EDI-OCT images

Annual International Conference of the IEEE Engineering in Medicine and Biology Society IEEE Engineering in Medicine and Biology Society Annual International Conference, 2012
Enhanced Depth Imaging (EDI) optical coherence tomography (OCT) provides high-definition cross-sectional images of the choroid in vivo, and hence is used in many clinical studies. However, measurement of choroidal thickness depends on the manual labeling,

A Texture-Based Method for Choroid Segmentation in Retinal EDI-OCT Images

Lecture Notes in Computer Science, 2015
Retinal layers can be identified by ophthalmologists using OCT images, which is useful for the diagnosis of different diseases. Recent EDI-OCT technique allows to explore the choroid layer, whose segmentation has become one of the hottest topics in the field of retinal imaging. In this sense, and taking into account that the choroid layer has different

Enhanced depth imaging OCT (EDI-OCT) findings in acute phase of sympathetic ophthalmia

International Ophthalmology, 2015
The purpose of this study was to describe the EDI-OCT findings in an acute phase of sympathetic ophthalmia (SO). A 24-year-old gentleman was referred to clinic complaining of progressive blurry vision of his right eye within last 3 days. He had a history of repaired corneoscleral laceration in his left eye followed by lensectomy and anterior vitrectomy

GMM cluster based choroid segmentation in EDI OCT images

2017 International Conference on Computing Methodologies and Communication (ICCMC), 2017
The structure of Choroidal layer can reflect many diseases such as polypoidal choroidal vasculopathy and choroidal tumors; hence proper segmentation of this layer is a major task. Also the assessment of choroidal thickness from Enhanced Depth Imaging (EDI-OCT) image is an important basis for diagnosing. Mostly this is done by manual labeling which is a
